[FIXED] Maptools won't display interface.

[rfandom]

Upon running either this line of code in a terminal, or trying to launch Maptools from launcher:

Code: Select all

java -Xms64M -Xmx512M -Xss2M -DMAPTOOL_DATADIR=../.maptool -jar maptool-1.4.0.0.jar run

(this applies to all versions, not only 1.4, I tried also 1.3.b84 and 1.3.b91). I'm using the zipfile from the official site.

All that is displayed is a grey-yellow window intead of Maptools interface. The interface seems to be responsive ie. if I click on it wildly enough, some pop-up window might appear. On the included screenshot you can see the closing window which is activated upon pressing the close-window shortcut (which is equivalent to alt+F4 on windows).

I'm using Linux. java -version output

Code: Select all

java version "1.7.0_91"
OpenJDK Runtime Environment (IcedTea 2.6.3) (Gentoo icedtea-7.2.6.3-r2)
OpenJDK 64-Bit Server VM (build 24.91-b01, mixed mode)

I have no idea what is the problem as I get no errors of any kind that might be related to a problem. Running the program with --verbose shows nothing significant. This is not related to my graphic drivers or a graphical configuration, as I can flawlessly run applications that use OpenGL, 3D or 2D, including java applications.

Maptool doesn't work properly with OpenJDK. Usually it works better than you've described, but even if you can get it to open, lots of things will be odd. You should get the Sun JRE and uninstall openJDK. Also get Java 8.

The same thing is happening even though...

java -version

Code: Select all

java version "1.8.0_72"
Java(TM) SE Runtime Environment (build 1.8.0_72-b15)
Java HotSpot(TM) 64-Bit Server VM (build 25.72-b15, mixed mode)

Used the newest Java 8u72 as you can see in the output. Straight from the oracle website. So, what's the real problem?

[paulstrait]

Hmm. I'm not sure. Could you paste your log file?

[rfandom]

What log file? I'm posting you the output of the command with -verbose enabled.

There should be a log file in the .maptool hidden folder in your user directory.

There it goes.

Okay I found the problem and it has been solved. It was matter of my Window Manager being a problem for java. Adding ` _JAVA_AWT_WM_NONREPARENTING=1 ` environment variable solved it completely. Thanks for the help.

That's interesting. Is the Windows Manager in this case a product of the OS or a third party solution?
